Guide for Diamond Grinding Wheels Specifications


Straight:Straight wheels are grinding wheels that consist of abrasive grains bonded together by a matrix of resins, epoxy, rubber, metal, and vitrified glass materials. Straight wheels have a simple, flat, disc shape without any recesses, flaring or cups.

Cylinder:Cylinder grinding wheels are those with flat circular ends and long straight.

Tapered:apered body wheels have a thicker cross-section at the bore, which becomes thinner or tapers toward the outer diameter.

Straight Cup:Straight cups have a cup or bowl shape. They are referred to as "straight" because of their cylindrical configuration.

Flaring Cup:Flaring cups have a cup or bowl shape,because their sides flare out.

Dish:Dish wheels have a dish or saucer shape, such as ANSI type 12 wheels.

Other:Other specialty, proprietary, or patented abrasives or abrasive products.


Available diameter ranges from 16mm to 660mm.


Cylindrical /Centerless:Products are suitable for cylindrical or centerless grinding. Cylindrical grinding refers to grinding between the centers of shafts, threaded shafts, large rolls, cams, or similar components. With centerless grinding, cylindrical workpieces are placed between a grinding wheel and regulating wheels. The latter causes the part to rotate to produce precision cylindrical parts. Parts sit on a work rest rather than on centers for faster and easier insertion and removal of the workpiece. Centerless grinding is used primarily in high production applications. It has various forms, including through-feed and plunge grinding.

Internal /Bores:Internal grinding applications use smaller diameter wheels or other abrasive products for grinding or finishing the surface on a part's inner diameter.

Surface/Creep-feed:Products are designed or suitable for Blanchard, surface, or creepfed grinding applications.

Toolroom/Sharpening:Products are designed or suitable for toolroom, sharpening, or precision grinding applications.

Cutting-off:Products are designed or suitable for cutting-off applications.

Woodworking:Products are designed or suitable for woodworking applications.

Specialty:Products are designed or suitable for other specialty, proprietary or patented applications.

Abrasive Grain

Natural Diamond:Natural diamond, also called diamond, which is known as women’s decoration in ancient times. Actually, it refers to some crude material taking its shape through series of chemical reaction, such as in the volcano, where the molecular structure of the carbon element turned into a more stable one under high temperature and high pressure.
In natural diamond, the most common form of diamond crystals is octahedral, while a dodecahedron diamond is rare, cube more rare. In addition, there are many other shapes of convex octahedron, convex dodecahedron, convex hexahedron and their combination. Due to crustal movement, and the impact from the nature, surface crystal is more than the plane ones. On the surface of natural diamond crystal there are some ladder-shaped or uneven reliefs, sometimes appearing with some triangle shaped holes on the octahedral crystal and deep dark lines on the dodecahedron diamond crystal.
The formation and discovery of natural diamond are not easy, because it is a carbon’s transformation under such special conditions in the deep earth as high temperature and pressure after hundreds of millions of years.

Synthetic Diamond:Synthetic diamond is produced synthetically in a high temperature, high pressure process anvil press. Diamond is superabrasive grain with the highest known hardness and a cubic crystal structure. Diamond is used for grinding nonferrous metals, ceramics, glass, stone, and building materials. Diamond is not useful in grinding steel or ferrous alloys because carbon or diamond readily dissolves or reacts with iron. Diamond pastes are useful in ferrous polishing or lapping applications where heat and reactivity are not a factor. Diamond is susceptible to oxidation at higher temperatures (GS)
For cutting, drilling and shaping tools in the construction, stone and extraction industries, switching from conventional hard materials to synthetic diamond delivers the single biggest opportunity to raise productivity. If you are a tool maker, the sales advantages of faster, cleaner cutting and longer tool life far outweigh the investment in synthetic diamond. For end-user customers, synthetic diamond transforms site productivity, cuts power consumption and drives down costs. (E6)

Coated Diamond:Metal-clad abrasives have a metal layer or coating. Some superabrasive products use metal-clad grains to dissipate heat or enhance bonding.

Combination:The combination of several abrasive grains together.

Specialty:Other specialty, proprietary or patented abrasive grain or material types.


Available concentration ranges from 25% to 200%.

Bonding Agent

Vitrified:Products have a vitrified or glass bond system between the abrasive grains.

Resin:Products have a resin or resinoid bond system between the abrasive grains.

Metal:Products have an electroplated or brazed metal bond system between the abrasive grains, or between the grains in a metal substrate.

Electro-plated:Products have an electro-plated bond system between the abrasive grains.

Specialty:Other specialty, proprietary or patented bond types.

Work Condition

Dry:Products are designed or suitable for dry grinding applications.

Wet:Products are designed or suitable for wet grinding applications.

Dry/Wet:Products are designed or suitable for both dry and wet grinding applications.
